The Lowdown
Alright, Rusty here. Let’s talk through this in feet and miles.
Lakey Pipe is on the menu, and she’s looking like a solid run. This is a consistent, exposed SW reef break. Water temp is sitting at 80°F, pretty average for this time of year.
The swell starts Friday morning, September 4th, with a 5ft SW swell, but the SE breeze is a little crossed-off. It’s doable, but not the main event. Saturday the 5th is where it picks up: 6ft from the SSW, clean, with a 14-second period – that’s the green light. Saturday afternoon pushes 6ft at 16 seconds, still clean. Good for experienced surfers.
Sunday the 6th brings 7ft, but the conditions get a little cross-chop in the afternoon. Still plenty of size. The real standout runs from Monday the 7th through Wednesday the 9th. Monday holds around 7ft to 7ft, clean. Tuesday the 8th has an afternoon session with 5ft but an 18-second period – that’s some serious long-period groundswell, meaning powerful, lined-up waves on the reef. Wednesday the 9th morning is the big one: 8ft SSW, 16-second period, and clean. That’s expert-only stuff.
The swell stays strong all the way through. Sunday the 13th is another peak: 6ft in the morning (18-second period) building to 8ft in the afternoon with clean cross-off wind. And on Saturday the 19th, we get a late spike: 7ft, 17-second period, with a glassy calm morning. That session is going to be magic.
Crowds are likely, but with this much quality, you’ll find your spot. Consistent SW groundswell, clean wind, and plenty of power. This is a great run.
Rusty.

Information about the Lakey Pipe Surf forecast
The above surf forecast table for Lakey Pipe provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Lakey Pipe can be found by selecting the local surf guide option on the grey menu. Our Lakey Pipe surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Lakey Pipe) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Lakey Pipe may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
